1 Thistinvention relates to mattresses, and particularly to mattressesused in the sick "room or hospital.

An object of the invention is to provide a mattress; composed of a pairof identically constructed se'ctions'having inner seamless ends.

Another object of the invention is to provide a two-part mattress, inwhich the bottom of each part is formed with straps adapted to besecured to'the springs of a bed so that the two parts of the mattresscan be arranged in any desired position with respect to each other onthe bed springs.

A further object of the invention is to provide detachable means forfixedly retaining a mattress on the springs of a bed.

With these and other objects in view, the invention consists in theconstruction, arrangement and combination of the several parts of whichit is composed, "as will be hereinafter more fully described andclaimed.

In the accompanying drawing:

Figure 1 is a perspective view of a bed and its spring showing atwo-part mattress of the present invention mounted on the bed spring,the outer end of one of the parts of the mattress being turned up tomore clearly show the bottom construction;

Figure 2 is an enlarged longitudinal section taken along the line 2-2 ofFigure 1;

Figure 3 is an inverted plan view of one. of the parts of the mattress;

Figure 4 is an enlarged section of a portion of the structure shown inFigure 2 illustrating the manner in which the mattress-holding clip isapplied to the mattress and to the bed spring; and

Figure 5 is a perspective view of the clip.

Referring to the drawing, the mattress includes a pair of sections IIand I2. Since the sections of the mattress are of identicalconstruction, a description of one will suffice for the other.

Each mattress section comprises a cover formed of two layers of sheetmaterial. The outside of the cover should preferably be formed ofsuitable water-proof material I3 and the inner layer of the cover shouldpreferably be formed of suitable woven fabric, such as mattress tickingor the like I4.

The top, one end and the bottom of the two layers of material comprisingthe cover of each mattress section are formed from single rectangularpieces of material, the fabric layer I4 being placed upon the waterproofmaterial I3 and 1 Claim. (01; 5-1) the two sheets of material foldedtransversely midway the length thereof to provide a top section I5,inner end wall I6 and bottom section II, having an outer-exposed surfaceof waterproof material I3 and an inner surface of the fabric I4. The topsection 15 is spaced a suitable distance from the bottom section I! byside walls I8 and an outer end wall I9. If so desired, the walls I8 andiQJmay'beformed from a single elongated strip of flexible fabric of thesame material as the inner layer I4. The side and end wall material hasa width corresponding substantially to the distance it is desired tospace the top I5 from the bottom H to provide an'envelope or casing forthe filling'material of the mattress. The meeting edges of the materialsused in forming the mattress cover are seamed and connected vby rows ofstitches 20, which extend around the 'edgesof the mattress in the mannershown in Figures 1 and 3. [The manner in which the "covers areconstructed is such that there are not any transverse seams at the inneror confronting ends I6 "of the "sections II and I2, these ends of thesections bein rounded or semicylindr'ical in contour, so as to becapable 'of remaining in cont-act with each other in any angulatedrelation of the sections to each other.

Disposed within each mattress section and entirely enclosed by the coverthereof is a iillins including a base in the form of a sheet of felt 2!and a padding 22 of resilient material superposed on the felt base andoccupying therewith the entire interior of the cover. The padding 22'ispreferably in the form of a. rectangular block of foam rubber having oneend thereof semicircular in shape so that when the filling is mountedwithin the cover, the inner end wall It of each mattress section will besemicircular in form, as shown in Figures 1 and 2.

Arranged transversely of the bottom of each mattress section II and I2,and disposed at a suitable distance inwardly from the outer end wall I9thereof is a strip of flexible fabric material 25 constituting areinforcing band. The material of the reinforcing band 25 is stitched tothe bottom section of each cover by a series of stitches 26 arrangedlengthwise of the band. At a suitable distance inwardly from each end ofthe reinforcing band 25, the stitches 26 are omitted so that gaps areformed therein to provide laterally spaced loops 28 in the band, asshown best in Figure 1. I

The loops 28 may provide. hand grip means by which the mattress sectionscan readily be picked ber preferably formed of a strip of flat springsteel bent at two points in its length to provide an upper leg 33,Figure 5, connected at end 34 to an intermediate leg 35, the latterbeing connected at its opposite end 36 to a lower leg 3'1. The extremity of leg 33 may be downturned, as indi cated at 38, Figure 5, andthe extremity of leg 3'! may be upturned, as indicated at 39.1The-construction and arrangement ofthe partsof each clip 3| is such thatthe upper'leg 33 is inserted in a loop 28 and arranged with said loop inthe manner shown in Figure 4, in which the end 34 of the clip engagesanedge of the band 25. With the mattress mounted on the bed spring 32, awire 40 of said bed spring is inserted in the space between theintermediate leg 35 and the lower leg 31 and the clip is then arrangedon the bed spring with the end 36 engaged by the wire 40.

In this way, the double hook provided by each clip 3| will be fixedlysecured to the mattress 4 in the central portion of a bed. This openspace or gap provides comfort for the patient and is useful to theattendant during certain kinds of care and treatment of certain types ofpatients. The open space between the sections of the mattress also isdesirable in the care of patients having bed sores that have developedon the patients back or hips, and by the proper use of this open spaceand the mattress sections the development of bed'sores canfbepreventedin almost all types of bedfast patients.

Still another important use of the mattress of the present invention isin the care and treatand will in turn fixedly secure the mattress in Vdesired position on the bed spring.

The ,mattress of the present invention and composed of two identicallyconstructed sections, is primarily designed to be used on hospital beds,The purpose of providing a sectional mattress of i the type hereinbeforedescribed is to enable each the sheets in bed making. a

The uses of the two sectional mattresses of the present invention areimportant when required during care, and treatment of certain types ofpatients, either half of the mattress being removable from the bed bydisconnecting its clips 31 from the bed spring wire to which they aresecured. Then the detached section can be disposed inapredetermined-position and secured in such predetermined position byengaging its clips 3! with the bed spring in the manner heretoforedescribed. Another use of the two-part mattress is obtained when thehalves are spaced apart to provide an openspace therebetween and ment ofpatients who have been placed in casts that encase the lower part of thebody from the These of the casts for certain purposes can be preventedbyarranging the sections of the mattress in the desired spaced apartposition on the bed spring.

The reason for forming the inner ends l6 of the sections H and I2 withrounded or semicir cular seamless surfaces is that a patient will nothave to lie on seams of the mattress when the sections thereof arearranged on the bed springs in the manner hereinbefore described.

Having thus described my invention, what I claim and desire to secure byLetters Patent is:

In combination, a bed spring, a mattress comprising a pair of mattresssections removably resting upon the bed spring in end-to-end relation,said mattress sections having semi-cylindrical confronting ends, thecurvatures of the confronting ends enabling the confronting ends toremain in contact with each other without distortion in differentangulated positions of the mattress sections relative to each other, andclip means acting between the mattress sections and the bed spring andsecuring the mattress sections individually in place.
